Flowmaster Super 44 Series Mufflers Reviews

The sound is awesome, mellow at idle with an aggressive growling rumble on acceleration that mellows out again at cruising speed. I would leave the stock resonator in because there is a slight 1700-2000 rpm drone if you don't. The truck gets plenty of compliments on the sound and has more low end torque.
